However, it is not necessary that a÷b or b÷a is also an integer. For example : Consider two integers 8 and 5. Clearly : (i) 8+5=13 is an integer. (ii) 8−5=3 is an integer 5−8=−3 is also an integer.

WebDec 5, 2024 · For two integers x and y, if xy=1 then x=y=1 or x=y=-1. Proof: then y = 1/x for x neither 1 nor -1 nor zero. then y is a proper fraction, a contradiction ===== Main theorem: integers a and b such that a b and b a; then a=b or a=-b. Note that neither a nor b can be zero, since they are divisors! since a b, a = nb for some integer n. WebShow that for all integers n : a) If d is an integer such that d?n+1 and d?n2+9, then d?10. b) If n is a multiple of 10 , then n+1 and n2+9 are coprime.
